Application filed July 23, 1915. Serial No. 41,573.

To all whom it may concern: I

Be it known that I, JOHN W. GRAHAM,

a citizen of the United States, residing at Hinton, in the county of Sumn'iersand State of West Virginia,, have invented certain new and useful Improvements in ly )ographical or Slug-Casting Machines, of which the following is a specification.

My invention relates to typographical machines, such as linotypes of the original construction, wherein circulating matrices are released from a magazine, in the order in which their characters are to appear in print, and then assembled in line together with expanding spacers, the composed line brought in contact with the face of a mold, the mold filled with molten metal, to form a line of type or slug against the face of the matrices, which produce the type characters thereon, and the matrices thereafter returned to the i magazines from which they were originally drawn.

More particularly it relates to that class of machines having a series. of magazines, in

connection with means whereby any magazine of the series can be brought into operative position, and locked therein, and in which the magazines are housed .in independent racks, andwherein theseries of magazines may be raised or lowered either by hand or power mechanism.

My invention is embodied in the new and novel construction of the frame mechanism which supports the magazines, and particularly in the feature whereby the magazine in operative position stands projected for ward, more than the other magazines of the series, and that this forward projection of the magazine is brought about by the circular travel of the magazine in being raised and lowered and not by any movement of the magazine after it arrives at the line of.

operative position, and this invention covers the feature that the magazines in their travel changetheir relative position one to the other as they hre moved up or down, and I also claim the feature whereby a dial is set for any desired magazine and the said magazine when it arrives in operative position, .is automatically locked therein, and i wherein the magazines are mounted on mov-.

able cam members whichalso guide the racks on their line of travel to exact operative position. v

In the drawings I have shown my invenin the claims.

. Referring to the drawings, Figure 1 is a side view of a portion of a linotype machine having my invention applied thereto. Fig. 2 shows a rear view of the forked arm A, having attached part of the raising and lowering. mechanism. Fig. 3 shows the power raising and lowering device. Fig. 4='sh0ws a worm gear wheel having attached a cog gear wheel used in the raising and lowering device. Fig. 5 shows the automatic locking device. Fig. ,6 shows part of the locking device. Fig. 7 is a view bf the cam or rack members which support the magazines. Fig. 8 shows a magazine housed in its rack. Fig. 9 is a side view of the parts shown in Fig. 8. V

Referring to Fig. 1,

A is a grooved supporting member having a rack thereon which supports the magazines.

A shows the pin on which bers A are hinged. I l c A shows the arm which houses the locking device.

B shows the'rollers on the racks (Fig.8). 7 g c shows the dogs which hold the mag C shows the loeliingdevice.

C shows the crank to set the automatic lock. (See Fig. I

C shows the dial finger or pointer used in setting the lock (Fig. 5).

C shows the dial.

C shows a shaft havingon one end a crank and on the other end the cog gear C shows a shaft having on it a thread' and also a cog gear Ci. C shows a strap having in t a slot, and

l) shows a pulley used in the power rais ing and lowering device.

I) shows the pin on which the casting D is pivoted.

D shows a lever.

D shows a pulley already on all machines oi the class described.

l shows the channel entrance. 7

F shows the escapement channel, the lower edges of the entrance and escapement channels being substantially in alinement with the pivots A Til shows the magazines.

in. operating the machine any of the magazine's can be brought into operative position by turning the crank on the shaft A When the said shaft is turned it operates the worm gearwheels A", and thecog gears immediately behind, and the cog gears are iulcrmeshed with the cogged surface of the supporting members and thus raise or lower the magazines.

In operating the power device. the lever l) at normal position holds both of the rollers l) free of the wheel D". The said lever can be moved so to bring either of the rollers D into contact with the wheel D, thus operating the shaft and its connected shafts A in either direction, and the shafts and A" and A being connected by bevel gears, themagaz rws are thus raised or lowered.

To operatethe locking device. the crank is turned until the linger (3 stands at desired number on the dial. The dial is numbered to correspond with the magazines, in this instance, 1, 3, l, and The slide is made of a thickness, such that the lock pins that rest on it do not protrude through the piece .1", but the said slide made near the center with a depression just wide eni'mgh to receive e head of one pin; iihen the said depressmn is set under any desired pin the said pin can drop into its 'corresponding hole in the supporting member A, when the said cam A is moved a suflicient distance to bring the said hole to position, but the other pins C havingtheir C are individually pressed inward by any desired spring mechanism, not shown. The gears on the shafts C and C, and the thread 'on the shaft G which engages the pawl on the slide C are so arranged that when the finger C ishrought to any desired number, the depression on the slide 0". is moved to the pin which corresponds with the-magazine whose number isdesignated on the dial C by the finger C. As soon as the finger on the dial is moved to a new number the magazines are unlocked, and the slide moves with its depression to anew pin and as it moves it withdraws the pin already engaged.

It is to be noted that the points of sup port of the several magazines as well as the lock pin holes are closer together near the.

center than at the top and bottom when measured along an arc. This permits a greater number of magazines to be supported in a device of this general construction than could be obtained if the distances between the magazine racks were made equal.

Having described my invention, its construction and operation, what I claim and desire to secure by Letters Patent of the l'i'nited States, is as follows:
